Mathematics Intervention for First- and Second-Grade Students With Mathematics Difficulties: The Effects of Tier 2 Intervention Delivered as Booster Lessons

Description

This study examined the effects of Tier 2 intervention in a multitiered model on the performance of first- and second-grade students who were identified as having mathematics difficulties. The study used a regression discontinuity design. Participants included 126 (Tier 2, n = 26) first-graders and 140 (Tier 2, n = 25) second-graders. Tier 2 students received 15-minute intervention booster lessons for 18 weeks in early mathematics skills and concepts. Results showed a significant intervention effect for second-grade Tier 2 students on the Texas Early Mathematics Inventories – Progress Monitoring total standard score. The effect was not significant for first-grade Tier 2 students.
